Description

Technical Field

[0001] This utility model relates to the field of air smoke detection technology, and in particular to an optical fiber air smoke detection system for irregularly shaped smoke storage facilities. Background Technology

[0002] The existing empty smoke detection device cannot be equipped with mechanical probe-type or simple photoelectric sensors due to space limitations and the special structure of irregularly shaped cigarettes. This causes the packaging machine for irregularly shaped cigarettes to keep running when the smoke is empty, doubling the problem of missing cigarettes in the mold box. That is, when the smoke warehouse is empty, at least 9 cigarettes in the following mold boxes will be rejected after a missing cigarette box, resulting in a lot of waste. It can also cause smoke blockage in the lower smoke warehouse, resulting in broken or residual cigarettes and causing quality accidents. The adjustment time after a missing cigarette box is long, and every three rejections will trigger the equipment to stop, resulting in an increase of about 100% in the average daily downtime and a serious decrease in production efficiency. Summary of the Invention

[0003] This invention provides a fiber optic empty smoke detection system for irregularly shaped cigarette storage, which can solve the problem that the existing irregularly shaped cigarette packaging machine structure cannot be adapted to small square cigarettes, and the empty smoke status cannot be accurately identified, resulting in frequent shutdowns of the existing irregularly shaped cigarette packaging machine.

[0004] According to one aspect of this utility model, a fiber optic smoke detection system for irregularly shaped smoke chambers is provided, comprising: a four-channel irregularly shaped smoke chamber, a fiber optic probe, a digital display controller, and a PLC (Programmable Logic Controller).

[0005] Each channel in the four-channel irregular-shaped smoke storage unit includes five sub-smoke channels. One fiber optic probe is aligned with one sub-smoke channel. The fiber optic probe is connected to the digital display controller, which is connected to the PLC.

Each channel in the four-channel irregular smoke chamber can include five sub-smoke channels, with one fiber optic probe aligned with one sub-smoke channel.

[0023] Example 1

[0024] Figure 1 This is a schematic diagram of the structure of an optical fiber smoke detection system for an irregularly shaped smoke storage facility, provided in Embodiment 1 of this utility model. The optical fiber smoke detection system for the irregularly shaped smoke storage facility includes: a four-channel irregularly shaped smoke storage facility, optical fiber probes, a digital display controller, and a PLC; each channel in the four-channel irregularly shaped smoke storage facility may include five sub-smoke channels, with one optical fiber probe aligned with one sub-smoke channel. The optical fiber probes are communicatively connected to the digital display controller, and the digital display controller is communicatively connected to the PLC. Figure 1 In the four-channel irregular smoke storage of the Chinese side, rectangles represent sub-smoke channels, circles represent fiber optic probes, and triangles represent digital display controllers. Due to the limited area of ​​the graphic, the names of all components are not labeled.

[0025] The four-channel irregular-shaped cigarette storage unit can be a small square cigarette storage unit with four sets of cigarette outlet channels. Each small square cigarette consists of four rows of five cigarettes. Sub-channels can be channels for transporting single cigarettes, formed by sub-channel separators arranged at certain intervals. The digital display controller can be an electronic device integrating digital display and control functions.

[0026] In an embodiment of this invention, the existing conventional cigarette packaging machine's lower cigarette storage structure can be modified into a structure with four channels, each channel including five sub-channels, resulting in a four-channel irregularly shaped cigarette storage unit to accommodate small square cigarettes. An optical fiber probe is positioned at each sub-channel of the four-channel irregularly shaped cigarette storage unit, and each optical fiber probe is communicatively connected to a digital display controller. The digital display controller identifies and displays the detection results of the optical fiber probes based on their detection signals and sends the results to the PLC.

[0027] Specifically, when the fiber optic empty smoke detection system for the irregular-shaped smoke storage is powered on, the fiber optic probes, digital display controllers, and PLC are initialized to ensure that all parts are in normal working condition. Each fiber optic probe continuously detects the status of the cigarettes in the corresponding sub-smoke channel according to a preset time interval, converts the detected analog signals into digital signals, and transmits the converted digital signals to the digital display controller. The digital display controller determines the status of the sub-smoke channel based on the received digital signals and displays them, and then sends the status identification results of the sub-smoke channel to the PLC. The PLC then controls the shutdown of the small square cigarette packaging machine based on the status identification results of the corresponding sub-smoke channels sent by all the digital display controllers.

[0028] For example, when the PLC detects that the status recognition result of any digital display controller for the sub-channel is empty, it needs to control the small square cigarette packaging machine to stop.

[0029] The technical solution of this utility model embodiment comprises a fiber optic smoke detection system for a non-standard smoke chamber, consisting of a four-channel irregular smoke chamber, fiber optic probes, a digital display controller, and a PLC. Each channel in the four-channel irregular smoke chamber can include five sub-smoke channels, with one fiber optic probe aligned with one sub-smoke channel. The fiber optic probes are communicatively connected to the digital display controller, which in turn is communicatively connected to the PLC. In this solution, each sub-flue is detected by a fiber optic probe, and the detection results are displayed intuitively through a digital display control module. The working status of the fiber optic probe can also be controlled independently, enabling individual detection and control of the empty smoke in each sub-flue. Furthermore, the four-channel irregular-shaped cigarette storage is compatible with small square cigarette packaging, allowing for timely shutdown of the packaging machine when empty smoke is detected, reducing the problem of missing mold boxes and avoiding significant waste of cigarettes. This solution solves the problem that existing irregular-shaped cigarette packaging machines cannot be adapted to small square cigarettes, and the inability to accurately identify the empty smoke status leads to frequent shutdowns. It is compatible with small square cigarettes, enabling high-precision, individually controllable empty smoke detection of the lower cigarette storage, making it more user-friendly for the efficient, safe, and reliable operation of irregular-shaped packaging machines.

[0030] Example 2

[0031] In one optional embodiment of this utility model, the fiber optic probe is a ceramic-encapsulated fiber optic probe with a diameter of 3 mm.

[0032] Currently, the mechanical probes used for air smoke detection have a diameter greater than 5 mm, making them unsuitable for 4x5 channels. A 3 mm ceramic-encapsulated fiber optic probe, however, can be used, adaptable to the channels of a four-channel irregularly shaped smoke chamber. In this four-channel irregularly shaped smoke chamber, each channel's sub-channels are divided by two sub-channel partitioning components at a certain interval.

[0033] Figure 2 This is a front view of a square-shaped, four-channel, irregularly shaped smoke chamber provided in Embodiment 2 of this utility model. Figure 2 As shown, the square-shaped four-channel irregular smoke chamber may include a first diversion component and three second diversion components; the geometric center of the first diversion component and the projection point of the channel center on the vertical plane are located on a straight line, and a second diversion component is installed between the two sets of channels.

[0034] Among them, the first diversion component and the second diversion component are two components with different shapes and structures in the square cigarette four-channel irregular cigarette box, which are used to divert the cigarettes in the square cigarette four-channel irregular cigarette box.

[0035] In this embodiment of the invention, a second flow-guiding component and a first flow-guiding component can be installed on the back plate of the four-channel irregular-shaped smoke chamber. The geometric center of the first flow-guiding component and the projection point of the channel center on the vertical plane are located on a straight line, and the geometric center of the first flow-guiding component is located above the channel center of the four-channel irregular-shaped smoke chamber. A second flow-guiding component is installed between two sets of channels, and the center between the middle two sets of channels is the channel center.

[0036] In one optional embodiment of this invention, the first drainage component can be a rhombus shape, and the second drainage component can be a triangular prism.

[0037] In an optional embodiment of this utility model, the digital display controller may include an optical fiber controller and a digital display module.

[0038] The fiber optic controller can identify whether a corresponding sub-flue is empty of smoke by using signals transmitted from the fiber optic probe. The fiber optic controller receives the signals collected by the fiber optic probe, performs logic processing, and outputs control signals. It can enhance the optical signal output by the fiber optic probe, improving detection sensitivity and stability. The digital display module can be a module with both text and graphic display functions.

[0039] In this embodiment of the invention, the fiber optic controller amplifies, filters, and digitizes the signal collected by the fiber optic probe, and identifies whether the corresponding sub-flue is empty by comparing it with a preset threshold. The digital display module is communicatively connected to the fiber optic controller and is used to intuitively display the empty status of the corresponding fiber optic controller in digital, text, or graphical form for real-time monitoring by operators.

[0040] Optionally, an optical coupler can be added between the fiber optic probe and the fiber optic controller to ensure efficient transmission of optical signals.

[0041] After handling the empty smoke issue, the operator can manually reset the fiber optic smoke detection system in the irregular smoke storage area.

[0042] Optionally, the fiber optic controller may include at least one processor and a memory, such as ROM or RAM, communicatively connected to the at least one processor. The memory stores computer programs executable by the at least one processor. The processor can perform various appropriate actions and processes based on the computer programs stored in the ROM or loaded into the RAM from memory units. The RAM may also store various programs and data required for the operation of the fiber optic controller. The processor, ROM, and RAM are interconnected via a bus. An I / O interface is also connected to the bus. The ROM is a read-only memory, the RAM is a random access memory, and the I / O interface is an input / output interface.

[0043] A processor can be a variety of general-purpose and / or special-purpose processing components with processing and computing capabilities. Some examples of processors include, but are not limited to, central processing units, various special-purpose artificial intelligence computing chips, various processors that run machine learning model algorithms, digital signal processors, and any suitable processor, controller, microcontroller, etc.

[0044] In an optional embodiment of this utility model, the fiber optic smoke detection system for irregularly shaped smoke storage rooms may further include an adjustable mounting bracket, with the fiber optic probe mounted on a movable mounting plate of the adjustable mounting bracket, and the movable mounting plate used to move the fiber optic probe up and down.

[0045] The adjustable mounting bracket can be used to align the fiber optic probe with the sub-flue, allowing for positional movement of the probe. The mounting plate is a trapezoidal plate with mounting holes.

[0046] In this embodiment of the invention, the fiber optic smoke detection system for irregularly shaped smoke storage can also be configured with an adjustable mounting bracket. The fiber optic probe can be mounted on the mounting plate of the adjustable mounting bracket, and the fiber optic probe can move up and down with the mounting plate.

[0047] The mounting plate may include a trapezoidal base plate with mounting holes (for mounting fiber optic probes) and two positioning clips located on the left and right sides of the base plate for fixing the mounting plate in position, i.e., fixing it to the flue gas separator assembly.

[0048] In an optional embodiment of this utility model, the mounting plate may further include a rotary thread, which drives the fiber optic probe to move back and forth.

[0049] In this embodiment of the invention, a rotary thread can be provided on the mounting plate, and the positioning buckle can be in the form of a lead screw, that is, when the lead screw is screwed in and out of the rotary thread, the fiber optic probe moves back and forth.

[0050] Optionally, a pivot can be installed on the mounting plate to drive the fiber optic probe to rotate at an angle.

[0051] In an optional embodiment of this utility model, the fiber optic probes of five sub-channels belonging to a group of channels of a square smoke storage four-channel irregular smoke chamber are aligned and connected to a digital display controller and assembled together.

[0052] In this embodiment of the utility model, the output lines of the fiber optic probes aligned with the five sub-channels of a group of channels in a square smoke storage four-channel irregular smoke warehouse can be consolidated, and the digital display controller connected to the fiber optic probes connected to the group of channels can be assembled together for operation and maintenance.

[0053] The connection relationship between the four channels of the four-channel irregular-shaped tobacco storage and the digital display controller can be found in [reference needed]. Figure 3 .

[0054] In an optional embodiment of this utility model, the PLC is communicatively connected to the irregular cigarette packaging machine.

[0055] In this embodiment of the utility model, when the PLC identifies that the status identification result of any sub-channel sent by the digital display controller is empty, it sends a stop control signal to the special-shaped cigarette packaging machine. The special-shaped cigarette packaging machine stops immediately after receiving the stop control signal.

[0056] Optionally, after each fiber optic controller determines that the corresponding sub-channel is in an empty smoke state, it sends the empty smoke state identification result to the PLC. The PLC can collect all the empty smoke state identification results sent by the fiber optic controllers and perform information statistics and summary.

[0057] In a specific example, a ZB45 hard-pack packaging machine can be modified to accommodate irregularly shaped small square cigarette packaging. Traditional empty cigarette detection devices are difficult to install, leading to frequent cigarette mold box shortages, resulting in significant cigarette waste and long maintenance times. By modifying the structure of the lower cigarette storage channel and combining it with fiber optic probes, digital display controllers, etc., a digital display multi-channel independently controlled fiber optic empty cigarette detection system can be constructed to accurately detect the empty cigarette status of each channel, achieve independent control shutdown, facilitate maintenance, reduce waste, and improve production efficiency.

[0058] The working principle of the fiber optic empty smoke detection system for irregularly shaped cigarette storage rooms is as follows: The controllers of the 20 digital display controllers are NPN type with parallel outputs. When the cigarette storage room is detected to be normal, a high-level output is generated, indicating normal operation of the 28 points on the N10 control board. When empty smoke is detected, a low-level output is generated, indicating input at the 28 points on the N10 control board. The packaging machine then stops and issues a red "no cigarettes in the storage room" message. Specifically, a low-level signal is active at the 28 points on the N10 control board.

[0059] The irregular-shaped cigarette packaging machine features a 4x5 structure with four channels for irregular-shaped cigarettes. It is equipped with 20 fiber optic probes, five for each channel, precisely covering the cigarette positions in each channel to accurately detect the presence or absence of cigarettes, solving the problem of traditional devices being unable to adapt to irregular-shaped cigarette structures. It employs 20 digital display controllers, each corresponding to a fiber optic probe, enabling individual control of the empty cigarette status of each sub-channel. When an empty cigarette occurs in a sub-channel, the corresponding digital display controller allows operators to quickly identify the location and status of the problem, avoiding prolonged downtime for adjustments, significantly reducing maintenance time, and greatly improving production efficiency. The digital display controllers display the detection status of each sub-channel in real time on an LCD screen, intuitively presenting normal or empty cigarette status with digital indicators (on or off), facilitating timely problem detection and handling by operators, and improving the ease of operation and monitorability of the equipment.

[0060] Adjustable mounting brackets allow for flexible adjustment of position and angle according to the specific needs of different models of non-standard cigarette packaging machines, ensuring that the fiber optic probe is accurately aligned with the exit of the lower cigarette storage channel, thus enhancing the versatility and adaptability of the device.

[0061] Equipped with 20 fiber optic probes in a four-channel, 4*5 structure for irregularly shaped cigarette packaging machines, the system precisely covers each sub-channel, accurately determining the presence or absence of cigarettes. When an empty cigarette is detected, it can be promptly identified, preventing it from entering subsequent packaging processes and significantly reducing cigarette waste and production costs. Each channel is equipped with an independent fiber optic controller for individual control. When an empty cigarette is detected in a sub-channel, the problem can be quickly identified and easily resolved. The digital display module shows the detection status of each sub-channel in real time on an LCD screen, presenting it intuitively through digital changes (indicator lights on or off). Operators can quickly understand the equipment's operating status without complex operations, promptly identifying and handling empty cigarette issues, effectively improving the ease of operation and monitorability of the equipment, reducing management difficulty and labor costs. The adjustable mounting bracket allows for adjustment of its position and angle according to the needs of different models of irregularly shaped cigarette packaging machines. This makes the device not only suitable for current irregularly shaped packaging machines but also flexible for other similar irregularly shaped cigarette packaging machines, reducing equipment modification and adaptation costs and enhancing the device's versatility and market competitiveness. The unique design of the overall system structure, with its tight cooperation and rational connection between components, ensures the stability and reliability of the detection system from a hardware perspective. The independently controlled circuit connections, the functionality of the digital display module, and the structure of the adjustable mounting bracket together constitute a complete and efficient system capable of long-term stable operation, reducing equipment failures and maintenance frequency.

[0062] This utility model addresses the four core pain points in the empty cigarette detection of irregularly shaped cigarette packaging machines: "cannot fit, cannot measure accurately, cannot see, and cannot be adjusted". Through the innovative integration of fiber optic sensing and digital display control technology, it achieves a leapfrog upgrade from mechanical detection to intelligent detection.

[0063] Conventional probes are too large to fit in space, so this invention uses a 3mm miniature ceramic-encapsulated fiber optic probe that can be installed even with limited space and the special structure of irregularly shaped smoke.

[0064] The false detection rate of conventional "uncertainty" testing increases by 100% compared to this test. In this utility model, the fiber optic controller uses 850nm infrared light plus an adaptive filtering algorithm to make the false detection rate ≤0.1%.

[0065] Conventional testing methods are "invisible" and lack sensitivity displays, making it impossible to determine which sub-flue is experiencing a problem. This invention employs twenty integrated LCD digital display controllers to monitor the channel status in real time.

[0066] Conventional testing methods cannot independently adjust parameters (such as sensitivity) for individual flue gas ducts, resulting in low equipment adaptability. This invention supports independent activation / deactivation and sensitivity adjustment for single channels.

[0067] The technical solution of this utility model embodiment comprises a fiber optic smoke detection system for a non-standard smoke chamber, consisting of a four-channel irregular smoke chamber, fiber optic probes, a digital display controller, and a PLC. Each channel in the four-channel irregular smoke chamber can include five sub-smoke channels, with one fiber optic probe aligned with one sub-smoke channel. The fiber optic probes are communicatively connected to the digital display controller, which in turn is communicatively connected to the PLC. In this solution, each sub-flue is detected by a fiber optic probe, and the detection results are displayed intuitively through a digital display control module. The working status of the fiber optic probe can also be controlled independently, enabling individual detection and control of the empty smoke in each sub-flue. Furthermore, the four-channel irregular-shaped cigarette storage is compatible with small square cigarette packaging, allowing for timely shutdown of the packaging machine when empty smoke is detected, reducing the problem of missing mold boxes and avoiding significant waste of cigarettes. This solution solves the problem that existing irregular-shaped cigarette packaging machines cannot be adapted to small square cigarettes, and the inability to accurately identify the empty smoke status leads to frequent shutdowns. It enables high-precision, individually controllable empty smoke detection of the lower cigarette storage, making it more user-friendly for the efficient, safe, and reliable operation of the packaging machine.
